RAILROAD-TIE.

Specification of Letters Patent.

Patented Sept. 26, 1905.

Application filed February 14, 1905. SerialNo. 245,572.

To all whom it may concern;

Be it known that I, JOHN G. SNYDER, a citizen of the United States,residing at Altoona, in the county of Blair and State of Pennsylvania,have invented certain new and useful Improvements in Railroad-Ties, ofwhich the following is a specification.

My invention relates to improvements in railroad-ties, and one object isthe provision of a railroad-tie which will be very durable or have avery long life, rendering the tie more desirable and economical, allmatters considered, than the ties in general use.

Another object of my invention is the provision of a railroad-tie whichwill form a perfect support for the rails, allowing for the necessaryexpansion and contraction and which will provide a perfect cushion andnoisedeadener for the rails, thus insuring a railroad-tie combiningevery requisite to render the tie thoroughly practical and efiicient inevery particular.

To attain the desired object, my invention consists of a railroad-tieembodying novel features of construction and combination of parts,substantially as disclosed herein.

Figure 1 represents a vertical longitudinal sectional view of one end ofmy railroad-tie. Fig. 2 represents a plan view with one of theconnecting and fastening plates removed; and Fig. 3 represents a planview of several ends of the ties with a rail in position or, in otherwords, a plan view of the complete improvement.

In the drawings the letter A designates the hollow casing or jacket orshell of my tie, which is preferably made of metal, and particularly ofsteel, and this casing is formed near each end with the recesses B,which are formed by the vertical walls C, said walls being formed attheir upper edges with shoulders D, in which are adapted to fit thesecuring-plates E, as will more fully appear.

The casing or shell is entirely filled with a substance, such asconcrete or other suitable material F, which will form a perfect solidmass whichrests upon the ground, and this construction provides the bedor support G, upon which rests the recessed chair H, in the recess orseat or socket J in which are placed e lower zinc or deadening plate Kand the intermediate lead plate K and the steel or the upperrail-supporting plate L, upon which rests the foot M of the rail, andthe connecting-plates or securing-plates E are retained in 'place uponthe chair and the walls of the tie by means of the verticalfastening-bolts N, the under side of the chair having kerfs N to securethe fastening-bolts from turning, and the plate E is provided with slotsO, which permit the sliding of the plate into position upon the foot ofthe rail.

From the foregoing description, taken in connection with the drawings,it is evident that I provide a railroad-tie which although initiallywill cost more than the ordinary Wood tie will last for so long a timeas to make it really cheaper than the ordinary tie; also, that the tieforms a perfect support for the rail and gives a cushion toinsure smoothand even riding and deadens all sound, and also that it can be easilytransported and assembled and that its use will fill a long-felt want ina perfect manner.

If desired, I may also place a lead plate under the plates that clampthe rail to the ties, and I have found by experience that the bestresults are obtained by usinga one-inch steel plate, a half-inch leadplate, and ahalf-inch zinc plate; but these proportions may be changed.

I claim- 1. A railroad-tie consisting of a casing or shell havingrecesses or chambers near each end, a filling or mass of material insaid casing forming a support and a bed under each chamber, a chairfitting in each chamber upon the said bed, and rails mounted andsupported upon said chairs.

2. A railroad-tie consisting of a casing or shell having recesses orchambers, a filling or mass in said casing forming a bed for saidchambers, chairs resting upon said bed and formed with recesses, adeadening-plate, an intermediate plate and a rail-supporting platearranged in the recess of the chair,rails mounted on the rail-supportingplates and means for securing the rails in position.

3. A railroad-tie consisting of a metal casing or shell and a filling ofsuitable material,

metal chairs resting upon the filling, deadenengaging the foot of therail and mounted ing' and supporting plates seated in said chairs uponthe chair and easing. 1 and a rail on the supporting-plate.
